data aggregation in wireless sensor networks: A comprehensive overview   Abstract: Wireless sensor networks frequently consists of a huge number of less expensive radar networks that rigorously partial detecting,computation and communique abilities.due to source regulated radar nodules,this one is essential to diminish the extent of data broadcast so that the normal radar life span and the global bandwidth operation exist upgraded.data transmission in the network.As wireless sensor systems are frequently

Abstract- Wireless sensor networks have been used in agricultural scenario because of the need for enhancing precision, quality and quantity in farming. This paper is about developing a prototype for the system which utilized a real time wireless sensor network to communicate wirelessly with a pest management system that measures the parameters air temperature and air humidity in an Apple farm for the prediction of disease, Apple Scab in Apple. For this purpose an application software has been

in a realistic wireless sensor network setting. Based on numerous proposed hierarchical routing infrastructures, we surveyed some hierarchical clustering algorithms and briefly discussed them. Main purpose of this paper is to present some recent hierarchical protocols and point out silent features of them. These routing protocols very much benefit in prolonging network lifetime and save energy of sensor nodes. Keywords: hierarchical protocols, clustering, wireless sensor networks, residual

Wireless Sensor Network (WSN) consists of a large number of low cost sensor nodes depolyed in parking area. These sensor nodes form a multi-hop ad-hoc network by wireless commnunication. Each sensor node detects whether the vehicle is parked, samples and transmits the information to base station where the information is gathered and processed. WSN can be applied to many other fields such as habitat monitoring, environment monitoring, smarthome, intelligent transportation and so on. The industrialization

1. INTRODUCTION Development in Wireless Communication and networking has led to development of many applications like Bluetooth, Near Field Communications and Wireless Sensor Networks. A wireless sensor network is essentially a network of nodes which consist of a power supply, sensors which usually sense the ambient conditions and processors for storing and processing information collected and a transceiver unit which is used to transmit and receive information from other nodes. In addition it might

ABSTRACT Wireless Sensor Networks are formed by autonomous nodes containing partial memory, better range of communication, power and capable bandwidth. WSN are used to inspect the corporal and environmental conditions through a system and perform data processing. However, during data acquisition different types of issues and circumstances are to be resolved. In this study, we have discussed about the data acquisition from wireless sensor networks having some faulty nodes. Here, we perform removal

Wireless Sensor Networks for Continuous Healthcare Monitoring BABATOLA FOLUSO FAHINA Faculty of Environment and Technology, University of the West of England. babsfash1@gmail.com Abstract— The healthcare monitoring applications of wireless sensor networks may require the properties of unobtrusiveness and continuity. The continuous tracking of the health state would address the challenges of caregiving for the elderly and performance checking for athletes during training. The application must

The MAC Protocols for wireless sensor networks are divided into two categories: 1. Contention-based: The Contention based protocols are used to avoid the hidden terminal problem. But the problems with these are idle listening, collision avoidance, and overhearing. IEEE 802.11, S-MAC are examples of this category 2. Reservation–based: TDMA protocols are based on reservation and scheduling. They have less energy-consumption compared to Contention based Protocols. Bluetooth is an example of TDMA based
